Why Choose the ABB 1SDA062808R1 T7L 1000 Circuit Breaker?
The ABB 1SDA062808R1 is a high-performance three-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax T7 range, engineered for demanding low-voltage power distribution applications. Identified as T7L 1000 PR332/P LSIRc In=1000A 3P F F, it combines a 1000 A rated current with ABB's advanced PR332/P electronic trip unit and residual-current protection.
The PR332/P LSIRc electronic trip unit provides comprehensive protection against overload and short-circuit conditions together with Rc residual-current protection. The overload protection is adjustable from 0.4–1 × In, equivalent to 400–1000 A, while magnetic protection is adjustable from 1.5–15 × In. The residual-current function provides an additional protection range of 0.2–1 × In.
The 1SDA062808R1 is supplied as a three-pole fixed circuit breaker with front terminals and lever operating mechanism. Its T7L construction provides an ultimate short-circuit breaking capacity of 120 kA at 380–415 V AC, making it particularly suitable for industrial switchboards, main distribution assemblies and high-current feeder circuits where high fault interruption capability and residual-current protection are required.

PR332/P LSIRc Electronic and Residual-Current Protection
The PR332/P LSIRc electronic trip unit combines adjustable overcurrent protection with residual-current monitoring. Its overload protection can be set between 400–1000 A, while the short-circuit protection range extends from 1500–15000 A. These adjustable settings allow the breaker protection characteristics to be coordinated with the electrical installation and other protective devices.
The additional Rc residual-current function detects current imbalance associated with leakage to earth and extends the protection provided by the breaker beyond conventional overcurrent protection. Combined with the T7L platform's 120 kA Icu at 380–415 V AC, this makes the ABB 1SDA062808R1 particularly suitable for high-current distribution systems requiring both substantial short-circuit interruption capability and residual-current protection.
Typical Applications
- Industrial low-voltage main distribution boards.
- High-current feeder and sub-main protection.
- Manufacturing and process plant switchboards.
- Commercial building main electrical distribution.
- Infrastructure and utility distribution assemblies.
- Installations requiring residual-current protection.
- Power distribution systems with high prospective short-circuit currents.
